 desc = "The remote host is missing an update to nas
announced via advisory DSA 1273-1.

Several vulnerabilities have been discovered in nas, the Network Audio
System.

CVE-2007-1543

A stack-based buffer overflow in the accept_att_local function in
server/os/connection.c in nas allows remote attackers to execute
arbitrary code via a long path slave name in a USL socket connection.

CVE-2007-1544

Integer overflow in the ProcAuWriteElement function in
server/dia/audispatch.c allows remote attackers to cause a denial of
service (crash) and possibly execute arbitrary code via a large
max_samples value.

CVE-2007-1545

The AddResource function in server/dia/resource.c allows remote
attackers to cause a denial of service (server crash) via a
nonexistent client ID.

CVE-2007-1546

Array index error allows remote attackers to cause a denial of service
(crash) via (1) large num_action values in the ProcAuSetElements
function in server/dia/audispatch.c or (2) a large inputNum parameter
to the compileInputs function in server/dia/auutil.c.

CVE-2007-1547

The ReadRequestFromClient function in server/os/io.c allows remote
attackers to cause a denial of service (crash) via multiple
simultaneous connections, which triggers a NULL pointer dereference.


For the stable distribution (sarge), these problems have been fixed in
version 1.7-2sarge1

For the upcoming stable distribution (etch) and the unstable
distribution (sid) these packages have been fixed in version 1.8-4.

We recommend that you upgrade your nas package.
